Modify RadSplitContainers view inside RadDocking

[Kostiantyn]

I would like to create different styles and templates for the RadDocking. My current problem is to that in the RadDocking panes which were places inside the DocumentHost will have header (button for dragging, closing pinning) at top, otherwise (left, right, bottom etc) RadSplitContainer & RadPaneGroup will place buttons at bottom. 

I would to place all of them at top, seems like I would to have same behavior as DocumentHost, but everywhere. Cause when I'm tried modified template of RadPaneGroup, and placed the buttons at first Grid.Row it's breaking behavior of RadPanes when you would to Drag them.

Is it possible to enforce other RadSplitContainers & RadPaneGroups behave like DocumentHost?
